G J <br />3. Allowable Leakage <br />a. Definition: Leakage is the quantity of water that must be added to the pipeline to <br />maintain pressure within 5 psi of the specified test pressure after the air has been <br />expelled and the pipe is filled with water. <br />b. Maximum allowable leakage: <br />L = NDf Pl ° s <br />148,000 <br />Where: <br />Q = quantity of makeup water, in gallons per hour <br />L = length of pipe section being tested, in feet <br />D = nominal diameter of the pipe, in inches <br />P = average test pressure during the hydrostatic test, in pounds <br />per square in.
